Left ventricle is the strongest and most important chamber of the heart. It receives oxygenated blood from left atrium, and pumps it into the aorta. Thus supplying the body with oxygenated blood. When this is said, all of the chambers are necessary for proper function of the heart.
Right Ventricle. The most posterior is the Left Atrium
The heart of a lamprey looks similar to that of modern fish in a sense. It is a two chambered heart with a single atrium and a single ventricle. The atrium of the heart is proceeded by a sinus venosus, which isn't considered an actual chamber but rather pre-heart chamber. Then after the ventricle we have a conus arteriosus that again isn't considered to be a chamber of the heart but rather a post-heart chamber. The blood flow through the heart is a one way path like that of modern day fishes.
Left ventricle
The left ventricle, it works the hardest and needs the most muscle mass.
The Systemic aorta is the major blood vessel that brings back blood to heart from most body parts.
The left ventricle is the thickest and most powerful chamber of the heart. It has to pump blood further (to the body) than the right ventricle (to the lungs).
The left ventricle is the largest and most muscular chamber of the heart.
Left Ventricle.
Right Ventricle. The most posterior is the Left Atrium
Atrium
there are four chambers in the heart. two are atriums and two are ventricles
The left ventricle is the largest chamber in the heart. It is responsible for pumping oxygenated blood to the rest of the body and has thicker muscular walls compared to the other chambers to withstand the pressure needed for systemic circulation.
The left ventricle of the heart takes up the most volume in the human body.

Systole and diastole most often refer to the ventricle of the heart. Systole is contraction of the ventricle, and diastole is the relaxation of the ventricle.
Left ventricle
The left ventricle is the heart chamber that most directly pumps blood to the vessel network. It pumps oxygenated blood out into the body through the aorta, which then branches out into smaller arteries to deliver blood to the rest of the body.
